India’s first private satellite that is co-assembled by Indian Space research Organisation (ISRO) with a private consortium is set for launch on Thursday.
Indian Space Research Organisation (ISRO) launched its first private satellite. A private sector-built navigation satellite IRNSS-1H from the Satish Dhawan Space Centre at Sriharikota on Thursday at 7 PM.
As per the reports, the launch of IRNSS-1H was necessitated following the malfunction of one of NAVIC’s seven satellites IRNSS 1A as its rubidium atomic clocks have failed. The atomic clocks are important to provide the accurate positional data.
The IRNSS-1H was built by a consortium led by Bengaluru-based Alpha Design Technologies under the supervision of a team consists of 70 scientists from ISRO.
Key features of IRNSS-1H
Like its other IRNSS predecessors, IRNSS-1H also carries two types of payloads – navigation payload and ranging payload.The navigation payload of IRNSS-1H will transmit navigation service signals to the users. This payload will be operating in L5-band and S-band.
The ranging payload of IRNSS-1H consists of a C-band transponder, which facilitates accurate determination of the range of the satellite. IRNSS-1H also carries Corner Cube Retro Reflectors for laser ranging.The launch vehicle PSLV-C39 will use the ‘XL’ version of PSLV equipped with six strap-ons, each carrying 12 tons of propellant.The over 1,400 kg spacecraft was built and tested by ISRO along with a consortium of six small and medium industries.
Alpha Design CMD HS Shankar said the consortium had bagged the orders to build IRNSS-1I and work had already begun. The launch of IRNSS-1I is scheduled for April 2018. Incidentally, in another first, a crucial part of the development of IRNSS-1H happened at the newly developed Isro space park in Whitefield.
Isro felt the need to launch IRNSS-1H after three atomic clocks of its first navigational satellite IRNSS-1A, launched in 2013, stopped functioning.
These rubidium atomic clocks, which are imported from European aerospace manufacturer Astrium,are meant to provide accurate locational data.
Isro had imported 27 sophisticated timekeepers for the nine satellites of the Rs 1,420-crore Indian Regional Navigation Satellite System (operational name NaVIC — Navigation with Indian Constellation).
